To all whom it may concern; ance conductor, separated from the ring Be it known that l., IJALTER C: Fist-r, a an insulating layer of mica e, rings of insu citizen of the United States, residing at lating material binding the coils together'l Lynn, in the county of Essex and State or" and further insulating the saine. A casing 5 Massachusetts, have invented certain neur 6 1s supported on ring 2 and insulating ringsV Aand useful Improvements in Electric Heat- 5, and'is secured to the former hy means of ers, of which the following is a specication. screw '7. `Legs 8, preferably three in'nurn- This invention relates to electric heating her, are 'secured to the. casing to support the devices and has for its object the provision of ring in a horizontal position. The terminals' l 0 a device of this character which will he incre 9 and IO oi' coil 3 are brought down .through pensive and eicient in operation, simple and insulating bushings l1 so as to reject belowconvenient of construction and at the saine the casing at a point adjacent t e handle l2. time, thoroughly reliafole, safe and durable. A protecting sleeve 13 oi' mica insulates the My invention relates incre specically to terminal from the turns of the coil, Which 15 electric heating devices to he usedin cooking. niay edgeivise, or any desired type. A In the culinary art as is Well known, a variety cooking utensil 1-4 having the lower portion of utensils is necessary. These, in thecase of 1.5 tapered to correspond with that of the cooking with a stove can oe-made up in a. taper 2 is adapted to lit into the ring. This very inexpensive Way, hut in the case of electaper causes a. Wedging action and results in 2G tric heaters, it has heen the practice toequip` an intimate thermal relation between the each utensil with ya heating means. This ring and the utensil, and also provides for a renders the devices expensive. Moreover, variation in the size the tapered portion ci i. the heating attachment renders them di'lie the utensil,

In Figs. a and 5 I -have shown a modified The object of my invention, therefore, is forni of my invention, in which hrrangernent to provideaheating base Which is adapted to I have shown, in addition to the electricreceive various utensils'.v In this case the heating equipment, fa' gas burner lf3, at utensils themselves inayheof the ordinary tachedto the hase by i. eans of support-ing; type and equipped with an outer surface bracket 17, or in any desired manner. This Y adapted to lit into the heating base. burner may he of any desired' type, but the vIn carrying out my invention, I provide an ordinary ring burner is Well adapted to this annular liase having a tapering inner surface construction, connection being made to a andv having a heating coil Wound around its 'flexible gas pipe through the nipple 18. outer surface for heating the same, The The arrangement is such that the device may utensils are then rnade s' as to have a correhe heated either hy the gasor by the elec' spondinglytapered outer surface and fit into heat, or by both, ifdesired. device or' close conductive relation with the hase. this character would A'oe convenient 1n cases In the drawing `which illustrates onef'eni- Where both gas and electricity are available bodiment of my invention, Figure 1 repre` for use as heating ineens and Where by acci@ sents an elevation of my cooking device ,1 dent or fro-rn other reasons one or the other Fig. 2 is an elevation of the hase'thereof, is rendered temporarily inoperative.

What l claim as new and desire to secure oyLetters Patent of the United States, is,

i. A11 electric cooking device comprising 'en' annuler bese having e smooth tapering surface end sup orted in an elevated positien, ineens for relating the seme, end rece tacle edepted to fit into intimate thermal rention with said base.

- 2. An electric cooking device comprising 'en annuler base' having e smooth teperinfv l inner surface and supported in en elevate position,electricel ineens' for heating the seine, end a receptacle adapted to fit into intimate thermal relation with said base.

3.`An electric cooking device comprising en annuler base having' a tapering inner surece end supported in en elevated position, en electric resistance in heet conductive reletion therewith, and 'e receptacle having e correspondingly tapered outer surface and adapted to 'lit into intimate thermal relation with said ring.

4. An electric cooking devieecomprising e. ring-shape heating base having e tapering inner surface, n resistance conductor wound v on the outer surface thereof, ineens for supporting seid ring in en elevated position, e receptacle having e similarly tapered outer portion adapted to lit into intima-te ther-mel relation with said ring.

5. An electric heater comprising a metallic ring having e smooth tapering inner surface, en electric resistance in neet conductive relation therewith, e support for seid ring whereby it is maintained in en elevated position end e supplementary 'heating device permanently secured to seid ring mounted so es to heet tne interior thereof.
